To all tbwm t may concern:

Be it known that I, EDWARD HALE BEL- DEN, a citizen of the United States, and a resident of Pittsburgh, county of Allegheny, and State of Pennsylvania, have invented certain new and useful Improvements in Intermal-Combustion Engines, of which the following is a specification.

My invention relates to internal combuslo tion engines and has particular reference to improvements in multiple cylinder internal combustion engines.

` The objects of my invention are to .in-, crease the power ethciency -and the dura- .bility of such engines; to decrease the'ncost of manufacture, to simplifythe construc- `tion, and to eliminate the vibration and noise due to the operation of such engines.

My further purpose is to provide a multiple cylinder internal combustion engine in which the auxiliarydriven mechanisms Shall be associated in a unitary arrangement whereby the structure of the engine as a whole is consolidated and simplified, and whereby the driving of the auxiliary mechanisms, including the main valves, is accomplished by a single power connection with the main driving shaft of the engine.

In a Simple form1 my invention resides in a multiple cylinder internal combustion engine, the cylinders being divided into two groups having a single valve shaft adapted to control the valves of all the cylinders, and a mechanism adapted to transmit power from the main shaft to the valve shaft, and arranged in the space between the two groups of cylinders.

My invention also resides in a multiple @vlinder engine having its cylinders assoelated ln two groups, and provided with an aufviliary or counter-shaft arranged longitudinally in relation to the engine, and from which all of the auxiliary driven mecha* nisms including the main valves, derive their power, and a driving mechanism conh necting the. counter' shaft with the main shaft of the engine, and ypreferably arranged between the two groups of cylinders. My invention also consists in the peculiar' association of auxiliary mechanisms, in the unique. features of construction, and in the arrangen'ients and combinations of parts and devices whereby the above mentioned and other objects are attained, and all as hereinafter described, and particularly pointed out in the appended claims.

vMy invention will be more readily understood by reference to the accompanying drawings which form part of this spccification, and in which; i

Figure l, is a side elevation of a multiple cylinder internal combustion engine illustrating one, a preferred, embodiment of my invention portions of the chain casingandot the base being broken away to disclose the valve driving chain belts Fig. 2, is an enlarged vertical, transverse sectional view on thc line 2-2 of Fig. 1; Fig. 3, is a sectional View similar to Fig. 2 taken on the line 3-3 of Fig. l; Fig. 4,- is a horizontal sectional View on the line 4 4 of Fig. 2; and Fig. 5, is a top plan vieW of the engine, partly broken away to show the preferred form of main valve.

I have here illustrated my invention as embodied in a water-cooled, six-cylinder engine of the vertical type particularly adapted for use in automobiles. Its cylinders A are arranged in vertical position and in two groups of three each; the cylinders of each group being arranged side by side and the two groups are cast on one block or casting B. I separate thc'two groups to provide an intermediate vertical space, C in which I arrange the mechanism for transmitting power from the/ main shaft of the engine to the valve shaft. The casting B which contains the cylinders, forms the upper part of the crank case D and is provided with a number of transverse walls D1 which carry or are provided with main bearings D2 in which the main driving shaft E is rotatably 1nounted. l

The casting B ends at substantially the center line of the main shaft, and I close its lower end and complete the crank case' by means cfa casing F which is secured to the casting'lby the bolts F1, and thereby I provide a 'substantially oil tight crank case. The shaft ll is provided with an individual crank pin El for each cylinder, and each individual crank pin is connected with its associatedpistons E2 by means of an individually connected rod, E3. i",

As is usual in this type of engine,tlie crank pins are equally spaced around the and when thisslight distortion of the crankl shaft is transmitted to the valves through the valve driving mechanism, it is apt to produce slight inaccuracy of valve operation resulting in various objectionable noises, vibrations and losses of power There are usually associated with an internal combustion engine installed in an automobile a number of auxiliary devices or mechanisms which it is necessary to drive at certain speeds relatively to the speed of the engine, and by means of my invention I am enabled to associate these devices inV a simple, compact arrangement which adds to rather than detracts from the appearance of the engine, and which greatly simplifies the necessary gearing for the attainment of the relative speeds necessary for the various devices.

Asshownjn the drawings, l preferably make use/ofasimple form of ported sleeve valve G of the form described and claimed in United States Patents Nos, 1,017,073 5, all of which were issued to .me February 13th, 1912, but it should be understood that my present invention is not limited to a construction which includes this specific form of main valve. This form of valve comprises an individual ported sleeve G for each of the cylinders, which is mounted in a valve space provided between the wall of the cylinder and the cylinder head G1. Each of the valves is provided, adjacent to its lower edge, with an annular gear G2, and the wall of the cylinder is cut away at one point A1 whereby access can be had tothe portion of the valve provided with the annular gear for the purpose of rotating the valve in its chamber.

For the rotationl of the valves l. provide a valve shaft H which extends along the upper part of the engine substantially parall of the main valves are likewise rotating.

I preferably provide each of the valves G with opposit'ely disposed ports G3. and the cylinder walls are provided with inlet and exhaust ports A3 and A4 respectively adapted to register with the valve ports (la as the valves are rotated.

The engine, as illustrated in the drawings, is what is known as a four-cycle engine.

This type of engine receives a charge of fuel into eachl cylinder once for each second revolution'of the main shaft, consequently, as the valves are each provided with two ports, it is only necessary to rotate the valves at one-fourth the speed of the main shaft. This relatively slow rotation or operation of the main valves assists in the production of a noiselessly running engine.

'lllie shaft H is mounted in suitable bearings H2 carried by the casting B, and I inclose the shaft in a continuous chamber or duct H formed in the casting-B and conipleted by means of a cover plate Ht, which extends substantially the whole length ofA the engine. F or the continuous.rotationfof the valve shaft, I preferably provide a driving mechanism which extends upwardly from the main shaft to the valve shaft and between the two groups of cylinders, and asillustrated in the drawings, this mechanism consists of a gear wheel H5 arranged upon the middle portion of the shaft H, the gear wheel E4 arranged upon the middle portion of the main shaft, and adjacent to one of the main bearings D2 and some form of power transmission mechanism connecting the two gears. I further provide an auxiliary longitudinal shaft J arranged at one side of the engine, and substantially midway between the main shaft and the valve'shaft. This shaft J is preferably arranged on the side of the engine which is opposite to that upon which the valve shaft ll is located, and it is carried in suitable bearings J1 and J2, which are mounted upon and form part of the main frame of the engine. I provide upon this shaft two gear wheels J3 and J4, the former being larger than the latter, and I drive it from the gear wheel Ff on the main shaft by means of a silent chain K1. The gear wheels E* and J3 are preferably so proportioned that the counter-shaft J is rotated at a slightly higher speed than the engine shaft. I connect the small gear wheel J4 of the shaft J with the gear wheel H5 on the valve shaft by means of a second silent chain K2, and l so proportion the gear wheels J4 and H5 that the valve shaft H runs at a considerlt will now be understood that by properly proportioning the gear pinions H1 to the gears formed upon the sleeve valves l can rotate the valves attheir proper speeds relatively to the main shaft of the engine.
